json – JSON encoding and decoding

This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: json.

This modules allows to convert between Python objects and the JSON data format.

Functions

json.dump

json.dump(obj, stream, separators=None)

Serialise obj to a JSON string, writing it to the given stream.

If specified, separators should be an (item_separator, key_separator) tuple. The default is (', ', ': '). To get the most compact JSON representation, you should specify (',', ':') to eliminate whitespace.

json.dumps

json.dumps(obj, separators=None)

Return obj represented as a JSON string.

The arguments have the same meaning as in dump.

json.load

json.load(stream)

Parse the given stream, interpreting it as a JSON string and deserialising the data to a Python object. The resulting object is returned.

Parsing continues until end-of-file is encountered. A ValueError is raised if the data in stream is not correctly formed.

json.loads

json.loads(str)

Parse the JSON str and return an object. Raises ValueError if the string is not correctly formed.
